George Radion in Australia has a database on Australian-made Jacks

This database is for vintage and classic Duco vehicle jacks.  Many of the photos and comments have been gleaned from Ebay and other sites.  I would be pleased to add photos and comments from anyone who has information on these jacks.

Please note that this information is accurate to the best of my knowledge, but I make no claims about authority on this subject. Use your own discretion when evaluating the accuracy of the information.

The values are normally taken from auction sites world-wide, but exclude postage.

Request to vendors: Please feel free to use the information from these databases in your adverts. An acknowledgement of the source would be most welcome. However, please do not twist any of the information. Where I say along the lines: 'May be for car X' please make this clear in your advert. An altered statement saying: 'It is for car X' will create false facts and misinformation. If you know for certainty a jack's heritage please contact me so that I can amend the entry. Thank you.

The name of ‘DUCO’ was used widely as a corporate marketing name by Brown Brothers Ltd., purveyors of cycle and automobile accessories. Jacks were offered from as early as 1902.

 

 

 

 

Duco Patent Car Jack

Description:

The description and unedited words (by me) that follow are courtesy of NewMoody. I will just add the casting words: On the body on one side THE DUCO PATENT JACK. On the other TYPE B.

This incomplete rack and pinion example, probably dates from before WW1. It stands at about 9in tall, closed, and about 16in open. The small, shaped base measures 2 3/4 in X 3 1/2in. ‘Type B’ probably refers to a weight capacity table.

The operation is unique. The handle engages, to the left, with a horizontal worm gear, which, in turn, engages with another worm. This, with vertical teeth, drives a co-joined worm, whose horizontal teeth  control the rising and falling of the rack. In short, a ‘rack and worms’ jack.

Missing from this example are the two ‘buttons’, which allow the two horizontal pawls, which secure the extension in operation, to open. Also missing, importantly, is the saddle which secures to the extension so that it can be used as a handle on setting up.

Duco Registered

Description:

This is a single piston hydraulic jack with a manual single screw extension. The screw cap is cast DUCO REGISTERED. It is 12.75 inches closed and 16.75 inches with both stages extended. The base is 4.25 inches square.

I have entered this jack immediately following the Desmo 202 as it seems to have some resemblance, particularly the locking cap and the brass locking ring for the manual screw extension. I would be interested to know if there was a business relationship between Desmo and Duco.
